I designed a board last year that needed intialization at power up too. I
used PIC microcontrollers to do the job right on the board. If you can
off-load certain tasks to microcontrollers, you can frequently greatly
reduce the demands on rt-linux too.
Another method would be to put your code in eprom at the end of the bios,
and place a jmp to your code at the 16 bit reset vector. after your code
does what it needs to the card, chain to the original boot-loader
vector. I wouldn't count on this doing any more than initilization.
